S72.036K Nondisplaced midcervical fracture of unspecified femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Nondisplaced midcervical fracture of unspecified femur, subsequent encounter for closed fracture with nonunion

Summary

A nondisplaced midcervical fracture of the femur is a break in the middle portion of the femoral neck (the region connecting the femoral head to the shaft) where the bone fragments remain in their normal alignment. This code applies to a subsequent encounter for a closed fracture that has developed nonunion, meaning the bone has failed to heal properly after an initial injury. The condition requires ongoing evaluation to address the nonunion and guide further management.

Causes

High-impact trauma, such as falls or motor vehicle accidents. Low-impact trauma in individuals with weakened bones (e.g., osteoporosis). Nonunion may result from inadequate immobilization, poor blood supply to the fracture site, or infection.

Risk Factors

• Advanced age, particularly in those over 65
• Osteoporosis or other bone density disorders
• Female gender, due to higher osteoporosis prevalence
• History of prior fractures or bone diseases
• Participation in high-risk activities (e.g., contact sports)
• Factors contributing to nonunion, such as smoking, diabetes, or nutritional deficiencies

Symptoms

• Persistent hip or groin pain
• Inability to bear weight on the affected leg
• Swelling, bruising, or tenderness around the hip
• Leg shortening or external rotation of the affected limb
• Limited range of motion in the hip joint
• Possible clicking or grinding sensations during movement

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to visualize the fracture and confirm nonunion. Additional tests, such as bone scans or MRI, may be used to evaluate bone healing and blood supply.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture
• Surgical intervention, such as internal fixation or bone grafting, to promote healing
• Physical therapy to restore strength and mobility
• Pain management with medications or other modalities
• Nutritional support or supplements to aid bone healing

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. Regular follow-up with imaging is necessary to monitor healing progress. Recovery may take several months, and some patients may experience long-term mobility limitations.

Complications

• Chronic pain or disability
• Avascular necrosis (loss of blood supply to the femoral head)
• Infection, particularly if surgery is required
• Malunion (healing in an abnormal position)
• Increased risk of future fractures

Lifestyle & Prevention

• Maintain a diet rich in calcium and vitamin D to support bone health
• Engage in weight-bearing exercises to strengthen bones
• Avoid high-risk activities that may lead to falls or trauma
• Use assistive devices, such as canes or walkers, if balance is impaired
• Quit smoking and limit alcohol consumption, as these can impair bone healing

When to Seek Professional Help

Seek immediate medical attention if you experience severe hip pain, inability to bear weight, or signs of infection (e.g., fever, redness, or drainage). Follow up with your healthcare provider if symptoms worsen or do not improve with treatment.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Ensure the medical record specifies the fracture type (nondisplaced midcervical), the encounter type (subsequent), and the presence of nonunion. Include details about imaging results, treatment provided, and any complications to support accurate coding.
